The second was the Quichua Pygmy marmosets are not included in any of the IUCN categories in the Red Data Book of Ecuadorian mam- mals; they are listed only in the CITES Appendix II (Tirira, 2001). However, based on the evidence we have gathered during almost seven years of research, we suggest that the status of this species needs to be revised. Indeed, the populations we have studied in northeastern Ecuador have been severely affected by live capture, noise pollution and habitat destruction (de la Torre et al., 2000; Yépez et al., 2003). These factors are related to the development of the petroleum industry, the continuous increase of human populations due to high reproductive and migra- tion rates, and the cultural loss which native communities are experiencing due to their rapid insertion into West- ern cultures (Ministerio del Ambiente et al., 2001). All these factors have altered the equilibrium of natural ecosys- tems and are negatively affecting the populations of pygmy marmosets. Live capture of pygmy marmosets, in particular, is a common practice of children and adults of many indig- enous communities. They are also eaten in some areas, or killed for target practice in others. We believe that these problems could be mitigated with a program of environ- mental education. We began such a program this year, directed to the children of the communities that live close to some of the pygmy marmoset populations we studied. Yépez Pablo Credit: Figure 1.
